The Feather M4 Express, gets a glow-up here with an upgrade to the SAME51 chipset which has built-in CAN bus support! Like its SAMD51 cousin, the ATSAME51J19 comes with a 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM.

At the end of the board we have placed a CAN transceiver chip as well as a 5V converter to generate 5V power to the transceiver even when running on battery. The two CAN signal lines and ground reference signal are available on a 3-pin 3.5mm terminal block. The chip and booster can be put to sleep for power saving. The built in CAN can read or write packets and has support in both Arduino and CircuitPython.

The Feather M4 Can Express also comes with a Mini NeoPixel and 2 MB SPI Flash storage. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
